Accessory alarm device (only single unit)
The alarm device signals an excessive high water level. It can
be installed subsequently. The float switch is fixed to the
pump handle (see the drawing at the front). The cable is pulled
through the vent pipe and sealed in the same way as the pump
cable. The alarm unit should be connected to a separate elec-
tric circuit, to ensure the operation in case of a pump fault. Al-
ternatively it can be equiped with our 9V-rechargeable battery
for off the line operation.
Accessory special ventilation
If the ventilation over the roof level is not possible, alternatively
the special ventilation consisting of a ventilation screen and 3
activated carbon filters can be installed above the T-piece for
the cable in the ventilation pipe. An assembly instruction ac-
companies the special ventilation.
MAINTENANCE
The tank, the float switches and the foot strainer of the pump
should be inspected regularly and cleaned if necessary.
To service the pump, please refer to the separate operating
instruction.
